hi abapers ,

what is the diff. between ooabap reporting and normal abap reporting ?

wat are the advantages of developing reports using class based. ?

thanks and regards,

Rajesh

u can find in this forun

or thses links

Advantages of Object Orientated approach

Easier to understand when the system is complex

Easy to make changes

Encapsulation - Can restrict the visibility of the data ( Restrict the access to the data )

Polymorphism - Identically named methods behave differently in different classes

Inheritance - You can use an existing class to define a new class

Polymorphism and inheritance lead to code reuse

Hi Rajesh,

Check a tcode ABAPDOCU.

Click on abapobjects.

You will see some reports for the same.

In this way you can figure out the difference betweem ABAP programming and OO ABAP programming.

Also as the above replys have given references to the links which will help you to differntiate between the concept.

Hi Rajesh,

In OO ABAP program is divided in to objects where as normal report program(procedure oriented) is divided int o sub-routines.

Please check the following links to understand OO ABAP.

Hi,

Diff bet OOABAP and normal ABAP......

1. Encapulation - Data Hiding .

2. Polymorphism - one method is acting as diffenent ways in differnet classes.

3. Inheritance- Inheriting the properties of one class(super ) to another (subclass)...

Hope Helpful

hi,

Features of oops:

Better Programming Structure.

Real world entity can be modeled very well.

Stress on data security and access.

Reduction in code redundancy.

Data encapsulation and abstraction

Hi rajesh,

there are many advantages of class based reporting over classical reporting .

mainaly using classes in your reports than function modules reduces your programming effort.

you can create multiple instances of a class but it will be tedious if you try to do multiple instantion using normal function modules.

performance wise also using classes is efficient.because when you call a function module from your program it will copy the entire function group. so using classes it will give better memory utilization.
